Question

how can a petri dish be used in chemistry?
it allows for catching and directing the flow of liquids.
it makes sure nothing can fly in or out of a beaker while mixing.
it is used for making different reactions visible in a wider space.
it creates a specific concentration and volume of a solution.

Explanation:

A Petri - dish has a flat and open - top structure which provides a wide surface area. In chemistry, it can be used to observe reactions as the flat surface allows for a clear view of what is happening in a wider space. The other options do not accurately describe the main use of a Petri - dish in chemistry.

Answer:

It is used for making different reactions visible in a wider space.
